Version 7.0

Enhancements

  • Bandwidth Throttle now supports up to 20MB input buffer

  • In multi-user mode, port reservation can now be performed via the REST API

  • Updated Start / End Point statistics, added individual / global port statistics reset, added individual / global port link reset (via right-click)

  • MPEG H.264 impairment re-implemented. Added H.265 dynamic payload and H.265 support

  • Added new Markov Packet Drop mode

  • Accumulate and Burst impairment how supports delay time of up to 1 second

Defect Fixes

  • Start Point packet duplication did not work correctly in some scenarios with real world traffic

  • Fixed Packet Corruptor enable / disable via REST API

  • Bandwidth Throttle and Delay re-enabled disabled impairments on map stop via REST API
